The 2014 Cadillac XTS received a handful of new features last summer, but fast forward to present day and the 2015 XTS gets even more updates. With all the extra goodies added to the full-size luxury sedan’s amenity list, the automaker claims the XTS is the most technologically advanced model in the brand’s history.

Perhaps the most noteworthy addition to the XTS is the standard built in wi-fi hotspot and OnStar with 4G LTE. The Wi-Fi hotspot comes with a three-month 3G trial and is activated once the car is turned on. Upper trim levels now get a revised rear-seat armrest that includes radio and sunshade controls, while they also get power-adjustable 22-way front seats with heat, ventilation, and massage functions. Nineteen-inch wheels also get a new design, while front-drive models can be equipped with an optional lane keep assist system. Power-folding side mirrors also appear on the options list, while new paint colors include Cocoa Bronze Metallic and Dark Adriatic Blue Metallic. When spec’ing out the XTS, owners can now opt for a Kona Brown interior with Jet Black accents or Open Pore Sapele wood trim.

Aside from the base model, the 2015 Cadillac XTS is comes in three other trim levels: Luxury, Premium, and Platinum. Those are powered by a direct-injected 3.6-liter V-6 rated at 305 hp and 264 lb-ft, and that power is sent to the front or all four wheels via a six-speed automatic transmission. Then there’s the XTS Vsport, which takes up a notch with a twin-turbo 410-hp, 369-lb-ft 3.6-liter V-6 paired to a six-speed automatic transmission. All-wheel drive is standard on VSport model, and they also get a slightly different front grille.
